For those that purchased a Thunderbolt 540 at OSH, Were you able to deduct the ignitions, FI, mech fuel pump and push rod from the standard build? I know you can't with the standard Lycoming purchase but the Thunderbolt staff at the show made it sound like this was no problem.

Just curious if this is really the case and T-bolt will be as flexible as the other engine builders going forward.

"Thunderbolt engines are Lycoming's brand of high performance, built-to-order power plants for Experimental aircraft. With Thunderbolt engines, customers get a genuine Lycoming engine that is factory built, factory tested and factory supported - with several popular options of fuel systems, ignition systems, performance enhancements and finishing options. These features come with every Lycoming Thunderbolt engine:

I went with bpe540 partly because of using showplanes cowl and balanced engine ect. Don't know if thunderbolt will fit showplanes cowl. Another major work is to fit airflow aircon compressor. Have to chop the intake plenum away to make compressor fit. Also have to cnc new adapter bracket between fm200 and cold air sump that about 1/2 inch shorter. Bottom of showplanes cowl interfere with intake plenum. All major work but will be nice once done.
